The Keysight / Agilent E4440A is a high-performance PSA Series spectrum analyzer designed to measure and monitor complex RF and microwave signals from 3 Hz to 26.5 GHz. Known for its precision, it delivers exceptional typical performance, including an absolute amplitude accuracy of ±0.19 dB, a third-order intercept (TOI) of +19 dBm, and a phase noise of -118 dBc/Hz at a 10 kHz offset (1 GHz). Frequency coverage can be extended to 325 GHz via optional external mixing. The platform supports 40 MHz or 80 MHz analysis bandwidth options for capturing complex signals and can be configured with up to 16 built-in measurement personalities.
